![ln(T- \frac{20}{200})=-0.11t \\ e^{ln(T- \frac{20}{200})}=e^{-0.11t} \\ T- \frac{20}{200} =e^{-0.11t} \\ T-0.1=e^{-0.11t} \\ T=e^{-0.11t}+0.1](https://tex.z-dn.net/?f=ln%28T-%20%5Cfrac%7B20%7D%7B200%7D%29%3D-0.11t%20%5C%5C%20e%5E%7Bln%28T-%20%5Cfrac%7B20%7D%7B200%7D%29%7D%3De%5E%7B-0.11t%7D%20%5C%5C%20T-%20%5Cfrac%7B20%7D%7B200%7D%20%3De%5E%7B-0.11t%7D%20%5C%5C%20T-0.1%3De%5E%7B-0.11t%7D%20%5C%5C%20T%3De%5E%7B-0.11t%7D%2B0.1)
Then, now that we have solved for T, we can evaluate and solve for t=20 minutes.
Your answer is 3x^2+14x+2 / x^3+5x^2+4x
4 slices
There are 5 pizzas, with 8 slices each. That means there are 5 x 8 = 40 total slices of pizza. Since there are 10 students, dividing the slices evenly between students means that each student gets 40/10 = 4 slices
